4、热环境的吸热量不大于制热工作的排热量的时候，循环环路中的水温度上升，到必定程度时运用冷却塔排出热量；反之循环环路中的水温度下降，到必定程度时经过辅佐加热设备吸收热量。本文主要介绍了10kw（制冷面积在6070平方米）水冷分离式风机盘管空调器的设计思路及主要部分的设计计算，先后定性的分析了制冷剂的选择、压缩机的选用、冷凝器的水冷换热方式的确定、蒸发器换热方式的确定、节流机构的选择以及相关辅助设备的筛选及相关计算。在定量和定性的计算上明确介绍了热力计算、蒸发器的设计计算、冷凝器的设计计算、节流机构的选择计算、水环系统管路的计算以及其他辅助设备的选择过程。关键词 水冷分离/压缩机/冷凝器/蒸发器/水环热泵 KLRFP-600I- WATER-COOLED FAN COIL SPLIT AIR CONDITIONERSABSTRACTReform and opening up for 30 years, along with the rapid development of Chinas economy, peoples living standards have improved treme

Especially in recent years people of the quality of life in the rapid development of real estate values and household central air-conditioning presented unprecedented boom.Water-cooling separate fan coil air is household central air-conditioners, professional belongs to the category of water loop heat pump. This kind of air-conditioning system is convenient adjustment, energy-savin

Its outdoor condenser part adopts water-cooled form, indoor evaporator adopts the traditional air-conditioning cooling form, refrigeration range is bigger, can be in household air-con
7、ditioner and general central air conditioning, and cost between flexible adjustment is not high, easy installation, so in recent years very rapidly cooled separate air conditioner. In this system, the water/air heat pump units in water, heating water heating source of loop; Unit, criterion with water refrigeration for row heat. When water-loop heat pump system is less than the heat heating operation when the heat heating operation, put the water temperature circular loop, to certain degree gives
8、 off heat using cooling towers; Whereas the water temperature drop circular loop, to certain degree absorbs heat through assisted heating equipment.This article mainly introduced the 10kw (refrigeration area in 60-70 square meters) water-cooled separate fan coil air conditioner design idea and main part of the design and calculation, successively qualitative analyses of refrigerant compressor choice, the selection and condenser cooling ways of heat determined, evaporator heat throttle body determination, the way the option and auxiliary equipment choice calculation. Quantitative calculation are introduced in detail in the thermodynamic calculation on the design calculation, the evaporator design calculation, the throttle body choice calculation, water ring system pipeline calculation and other auxiliary equipment selection process.KEY WORDS water-cooled separation，compressor，condenser，evaporator，water loop heat pump
